Abstract
Purpose The increasing surface area of green roofs (GR) may have a significant impact on the quantity and quality of urban drainage. However, the chemical quality of effluents produced by GR in comparison to atmospheric deposit and other roof surfaces has to date been poorly assessed. It is necessary to determine whether a green roof acts as a sink or source of pollutants. This work was conducted to study the capacity of four materials commonly used to build green roofs.
